New Mexico Marriage License: Requirements, $55 Fee, and Ceremony

A New Mexico marriage license costs $55, is issued the same day you apply at any county clerk’s office, and never expires once you have it in hand. Both partners must appear together with valid identification, but there is no waiting period, no blood test, and no residency requirement. You can hold the ceremony that afternoon or years later.

Who Qualifies to Marry in New Mexico

Both applicants must be at least 18, the state’s age of majority.¹ A 16- or 17-year-old who is not legally emancipated needs the written consent of both living parents named on the birth certificate, or a district court order authorizing the marriage for good cause on a parent or guardian’s request. Children under 16 can marry only by order of the children’s or family court division, and only in narrow circumstances such as establishing parentage or when a license applicant is pregnant.²

State law voids marriages between close blood relatives: parents and children (including grandparents and grandchildren of any degree), full or half siblings, uncles and nieces, and aunts and nephews. First-cousin marriages are legal in New Mexico; cousins are not on the prohibited list.³

Residency does not matter. Out-of-state couples and international visitors can apply at any county clerk’s office in New Mexico, and no medical exam or blood test is required.

What to Bring

Each applicant needs identification sufficient to prove identity and eligibility. A valid driver’s license, current passport, or certified birth certificate is commonly accepted. The statute does not fix a specific list; it leaves the standard at what satisfies the county clerk.⁴

Each applicant must also give a Social Security number. The clerk collects it strictly for child support enforcement and cannot share it outside that use.⁴

If your ID is in a language other than English, bring a certified English translation with the original. The translator should provide a signed statement of accuracy and qualifications. Notarizing the translation is not always required, but it avoids questions at the counter.

If you were previously married, you do not need to hand over a divorce decree, death certificate, or annulment papers. You will have to answer questions about prior marriages on the application. If your last marriage ended by divorce, you are not free to remarry until the judge has signed the decree and it has been filed with the district court clerk. There is no mandatory waiting period after a finalized divorce.

The $55 Fee

The license fee is $55, raised from $25 by legislation that took effect June 20, 2025. That amount covers issuance, acknowledgment, and recording of both the license and the marriage certificate.⁵ Accepted payment methods vary by county, so check with your clerk’s office before you go if you plan to use a card.

How the Application Works

Both applicants have to appear together, in person, at the same county clerk’s office during regular business hours. You cannot send one person ahead to start the paperwork. The clerk verifies identity, confirms eligibility, and processes the application on the spot.

There is no waiting period. The clerk hands over the license once the application is processed, and you can legally marry the same day.⁴ The license is valid statewide, so the ceremony can take place in any New Mexico county regardless of where you applied.

The license does not expire.⁴ If plans shift and the wedding gets pushed back months or years, the same license is still usable.

Who Can Perform the Ceremony

New Mexico recognizes three categories of officiant:

Any ordained member of the clergy. Officiants do not have to register credentials with any state agency before performing a wedding.
An authorized representative of a federally recognized Indian nation, tribe, or pueblo.
Active or retired judges, justices, and magistrates of courts established under the New Mexico Constitution, the U.S. Constitution, or state or federal law. Civil magistrates cannot charge a fee.

County clerks are not authorized to perform ceremonies, even though they issue the license.⁶ The statute defines solemnizing as joining two people in marriage before witnesses by means of a ceremony, so at least two witnesses must be present. Some counties require witnesses to be 18 or older.

New Mexico does not permit self-solemnization. The law requires that the marriage be performed by an authorized official, so you cannot sign the license yourselves and file it.⁶

After the Wedding

The officiant must return the completed license, signed by the officiant and your witnesses, to the county clerk within 90 days of the ceremony.⁷ The responsibility is theirs, not yours, but it is worth following up. Miss the window and the marriage may not appear in the county’s public records; the marriage itself is not necessarily invalid, but proving it happened without an official recording is a much harder problem.

Once the clerk records the license, the county issues a marriage certificate. That is the document you will need to change your name on a Social Security card, update a driver’s license, add a spouse to insurance, or open joint accounts. Order at least one extra certified copy when it is first issued; fees for additional copies vary by county but are generally modest.

Common-Law Marriage

You cannot create a common-law marriage inside New Mexico. Living together and holding yourselves out as married, for any length of time, does not produce a legal marriage under state law.⁸

A valid common-law marriage formed in a state that recognizes them, such as Colorado or Texas, will be honored here. New Mexico applies a rule of comity: a marriage valid where it took place is valid in the state. Polygamous marriages are the major exception and are not recognized regardless of where they were performed. If you need to prove an out-of-state common-law marriage, New Mexico courts apply their own evidentiary standards to whether the marriage was validly created under the other state’s law.⁸
